Epsilon sent us this message. It rings true to me. I whipped a longbow in every city. I forgot to take a screenshot of our situation, so look at the save. We are researching gunpowder, which is good, but Innovia has nationalism, so it looks like they are going for calvary. Thankfully they do not yet have military tradition or gunpowder, so we have some time. Epsilon wanted us to research divine right and trade it to them, but I said we had to research gunpowder because of the war. In the same message I thanked Epsilon for the warning. I canceled open borders with Innovia and sent them a PM saying why.
